The Baltimore mosque President Obama has chosen as the first U.S.-based mosque to visit during his presidency has deep ties to extremist elements, including to the Muslim Brotherhood.

The White House announced on Saturday that Obama will visit the Islamic Society of Baltimore (ISB) on Wednesday. He has visited several mosques overseas as president but has resisted visiting one in the homeland. The purpose of the trip, according to the White House, is to “celebrate the contributions Muslim Americans make to our nation and reaffirm the importance of religious freedom to our way of life.”
